2020-07-28[3.1.x] Fixed #31829 -- Used JSONField __contains lookup on key transforms.sage
Backport of 2d8dcba03aae200aaa103ec1e69f0a0038ec2f85 from master
2020-07-28[3.1.x] Fixed #31836 -- Dropped support for JSONField __contains and ↵Mariusz Felisiak
__contained_by lookups on SQLite. The current implementation works only for basic examples without supporting nested structures and doesn't follow "the general principle that the contained object must match the containing object as to structure and data contents, possibly after discarding some non-matching array elements or object key/value pairs from the containing object". Backport of ba691933cee375195c9c50f333dd4b2a3abbb726 from master.

Oracle. The current implementation works only for basic examples without supporting nested structures and doesn't follow "the general principle that the contained object must match the containing object as to structure and data contents, possibly after discarding some non-matching array elements or object key/value pairs from the containing object".

2020-01-09Fixed #21238 -- Fixed restoring attributes when pickling FileField and ↵Hasan Ramezani

with an invalid type.
2019-12-03Fixed #31046 -- Allowed RelatedManager.add()/create()/set() to accept ↵Baptiste Mispelon
callable values in through_defaults.
2019-12-03Simplified RelatedManager._add_items() a bit.Baptiste Mispelon
Added early return in RelatedManager._add_items() to decrease an indentation level.
2019-11-22Fixed #8467 -- Prevented crash when adding existent m2m relation with an ↵Simon Charette
invalid type. This was an issue anymore on backends that allows conflicts to be ignored (Refs #19544) as long the provided values were coercible to the expected type. However on the remaining backends that don't support this feature, namely Oracle, this could still result in an IntegrityError. By attempting to coerce the provided values to the expected types in Python beforehand we allow the existing value set intersection in ManyRelatedManager._get_missing_target_ids to prevent the problematic insertion attempts. Thanks Baptiste Mispelon for triaging this old ticket against the current state of the master branch.
2019-11-19Fixed #30987 -- Added models.PositiveBigIntegerField.Caio Ariede
2019-11-05Refs #30095 -- Added Field._choices_is_value().Hasan Ramezani
This allows fields classes to override the validation of choices' values.
2019-11-04Fixed #30931 -- Restored ability to override Model.get_FIELD_display().Carlton Gibson
Thanks Sergey Fedoseev for the implementation idea. Regression in a68ea231012434b522ce45c513d84add516afa60.
2019-10-31Refs #30095 -- Simplified Field._check_choices() a bit.Mariusz Felisiak
Using an internal is_value() hook to check whether Field.choices is iterable is misleading.
2019-10-23Fixed #29919 -- Fixed RelatedOnlyFieldListFilter crash with reverse ↵Dan Moore
relationships.
2019-10-21Fixed #20577 -- Deferred filtering of prefetched related querysets.Alex Aktsipetrov
Added internal interface to QuerySet that allows to defer next filter call till .query is accessed. Used it to optimize prefetch_related(). Thanks Simon Charette for the review.
2019-10-17Refs #12990 -- Moved CheckFieldDefaultMixin to the ↵sage
django.db.models.fields.mixins.
2019-09-24Removed some outdated backwards compatibility imports and misleading comments.Mads Jensen
EmptyResultSet moved in 46509cf13dbf049f75077981c29ef2c60b5a96ab. FieldDoesNotExist moved in 8958170755b37ce346ae5257c1000bd936faa3b0.

2019-09-09Refs #29444 -- Allowed returning multiple fields from INSERT statements on ↵Johannes Hoppe
PostgreSQL. Thanks Florian Apolloner, Tim Graham, Simon Charette, Nick Pope, and Mariusz Felisiak for reviews.
2019-09-09Fixed #30757 -- Added a system check to ensure max_length fits the longest ↵Nick Pope
choice.
2019-09-02Refs #28442 -- Adjusted related lookups handling of expression rhs.Simon Charette
Expressions should never be prepared as other Lookup.get_prep_lookup implementations hint at by returning early on the presence of the resolve_expression attribute. The previous solution was only handling lookups against related fields pointing at AutoFields and would break for foreign keys to other fields. It was also causing bidirectional coupling between model fields and expressions which the method level import of OuterRef was a symptom of.
2019-08-20Fixed #29979, Refs #17337 -- Extracted AutoField field logic into a mixin ↵Nick Pope
and refactored AutoFields. This reduces duplication by allowing AutoField, BigAutoField and SmallAutoField to inherit from IntegerField, BigIntegerField and SmallIntegerField respectively. Doing so also allows for enabling the max_length warning check and minimum/maximum value validation for auto fields, as well as providing a mixin that can be used for other possible future auto field types such as a theoretical UUIDAutoField.
2019-08-18Refs #28428 -- Made FileField.upload_to support pathlib.Path.Claude Paroz
2019-08-15Fixed #30449 -- Fixed RelatedFieldListFilter/RelatedOnlyFieldListFilter to ↵zeyneloz

2019-07-27Refs #28147 -- Fixed setting of OneToOne and Foreign Key fields to None when ↵Jon Dufresne
using attnames. Regression in 519016e5f25d7c0a040015724f9920581551cab0.
2019-07-25Fixed #30657 -- Allowed customizing Field's descriptors with a ↵Jon Dufresne
descriptor_class attribute. Allows model fields to override the descriptor class used on the model instance attribute.
2019-07-25Refs #30657 -- Made DeferredAttribute.__init__() to take a field instance ↵Jon Dufresne
instead of a field name.
2019-06-28Fixed #30400 -- Improved typography of user facing strings.Jon Dufresne
